Vaccination Trends and Challenges in Children and Adolescents

Vaccination in children and adolescents is a routine part of preventive healthcare, yet the uptake of several vaccines has declined or stalled in recent years. This has been linked to a mix of factors, including concerns about safety, trust in health services, access to appointments, and the increasing visibility of vaccine misinformation. Decisions around vaccination are shaped not just by individual beliefs but also by service organisation, communication practices, and wider social and economic conditions. As a result, differences in uptake remain closely tied to inequality.

This Special Issue will focus on current trends and challenges in childhood and adolescent vaccination. We will publish research that helps explain patterns of uptake and non-uptake and that examines practical ways of improving access, communication, and service delivery. We welcome empirical studies, reviews, and evaluations that address vaccination attitudes, experiences with services, intervention development, and policy implications across different settings and populations.
